Room controller

RXC10.1

RXC10.5

for chilled ceilings

, radiators, and VAV applications

with

LONMARK®-compatible bus communications

The RXC10 room controller is used for temperature control in individual rooms.

• For chilled ceilings, radiators, and VAV applications

• PI or PID control (dependent on application)

• Downloadable application software

• L

ONMARK®-compatible bus communications

• Integrated into the Desigo building automation and control system

• Control of thermic valve actuators, AC 24 V, PDM

• Operating voltage AC 24 V

1) PDM = pulse/duration modulated

Application

The RXC10 room controller is optimized for the control of chilled ceilings, radiator-type

heating, and VAV applications at individual room level.

The controller application is determined by downloadable application software, also

referred to simply as the “application”. The various applications and the associated

functions are described in detail in the Desigo RXC applications library

(V1: CA2A3810, V2:CA110300).

The controllers are delivered pre-loaded with basic application 00010.

The basic application, which contains only I/O module functions, is overwritten with the

definitive application in the commissioning phase. The RXT10 commissioning and

service tool is used for this purpose (see “Commissioning”).

Use as an I/O module In conjunction with a building automation and control system, the RXC10 controller can also be used as a universal input module, e.g. to register the room temperature from digital signals or a setpoint reset unit. In this case, the controller is loaded with basic application 00010. The inputs can then be interrogated via the building automation and control system.

Service pin The service pin is used to identify the controller in the commissioning phase. When the pin is pressed, the controller’s identification number is transmitted to the RXT10 commissioning and service tool. Disposal The devices are classified as waste electronic equipment in terms of the European Directive 2012/19/EU (WEEE) and should not be disposed of as unsorted municipal waste. The relevant national legal rules are to be adhered to.

Labeling Function test The labeling fields “Appl.” and “Loc.” are used to indicate the application actually loaded and the location of the controller, either in writing or by use of printed adhesive labels (see “Label” under “Mechanical design”). With all applications (including basic application 00010), the inputs can be interrogated and the outputs overridden using the RXT10 commissioning and service tool.

Parallel connection of several thermic actuators Up to 2 thermic actuators can be connected directly to the room controller. In the case of more than 2 actuators a power amplifier is required. The same principle applies to outputs Y2. Note that the simultaneous load on outputs Y1 and Y2 must not exceed 9.5 VA. Power consumption at input X1 of the UA1T: 0.5 VA. STOP Mixed operation: Connecting thermic actuators to the controller as well as to the power amplifier is NOT allowed.
